Project Unimog 6x6 - Cooper

[pera2008]

good eye! :)

Only notice that today. Took both rear axles to solve some friction issues and make them smooth(DIY axles have issues...) and only saw those missings bolts when putting back that wheel. funny you mentioned that

I?m building Zil 131 and it goes too slow for me. all is first time and a lot of things need redone . I will possibly never achieve such details you put there. I have to also test how axles will work together. Good luck with that and smooth progress

 

[cooper]

For some reason, I've never seen your zil thread...gave it a quick look and seems you're doing quite well. I'm adding details to mine but it's a lengthy process. I've built this truck, rebuilt it and now I'm adding or improving stuff as I go along, as the skills improve or the ideas appear (or patience )

 

[cooper]

Well, things are going slow...was anxious to get the metal stuff done to pass the bed to the lady who will do the tarp.

At first, I wanted to do only the front and rear arch like the real ones but all my reference photos were from 4x4s. This long bed would need one more,atleast that's what I think.

The archs are 4mm stainless steel and the rest 3mm. The feet are steel, brazed to the archs.Was planning to braze everything but I'm quicker with the TIG.

One more random detail for the 'mog

 

[klako]

Really nice build, love all the details

 

[cooper]

Really nice build, love all the details

thanks!


I live in a rough neighborhood

the new bed is going nicely. the tailgate it's almost painted and ready to be mounted and I have the tarp also ready(not shown because I took it off to mount the bench)


The bench seat,printed frame with wood boards

 

[cooper]

Printed a pair of improved functional tailgate hinges to be glued to the bed. They're printed in one piece, let's hope they hold

Tailgate with the hooks. Not shown, are the rubber stops(printed in TPU because scale :) )

First look at the tarp

 

[cooper]

Hi!

I'm on the final stretch of this bed.Just need to glue the planks of the seat and make the chassis mounts

Anyway, there's how it looks:

Closed latch

A printed hinge.

I'm very excited how it turned out.Anxious to get it on the trails

Awesome! Love the details, bench, rubber stops, tarp looks great too.

Nice job!

Because the truck has to function properly,I've improved the rear shocks to handle the extra weight.

The old ones weren't shock absorbers at all, were pretty and scale but there was no o-rings on the shaft so they couldn't hold the oil.

So , found these 60mm shocks for cheap and took the springs out and filled with 1000 oil:

They only problem is that they are made for m2.5 hardware and couldn't find 4.8mm balls for m3 so did these ones:

Another detail that was buggin me was mounting this tow hitch

Got the hitch from eBay, some M2 scale bolts and printed the frame around it


Don't mind the rust. It's almost ready to be painted

 

[2Beers]

Top notch .
Beautiful truck coming about.
Very drool worthy my friend.
Keep the pics and updates coming.

Suspension, all of it is beautiful

Thanks a lot! how cool was to do a trail run with both our 'mogs :)


Well,guys,in my opinion, 3D printing is cool but when we only print scale acessories, we're just scratching the surface of it's true potential

The Moose axles being released free maybe clicked in my brain and came back from an old idea of making a full axle for the unimog. The problem is that I like this truck but the ugly axles seem out of place. Adding to that the front axle is a Frankenstein that i don't know how it never failed

So,I've started to design from scratch,heavily influenced by the now discontinued SSD D60 axle housing.

This housing will have all the features of the old one like being 20mm narrower to compensate to portal boxes,panhard mount, spring perches,spherical ends, 7? of caster and 3rd link mount. The pumpkin is small as the stock gears allow...


Front:

back:

Diff cover will be designed next....

 

[cooper]

Progress:

had some M2 scale bolts laying around and I thought they could look nice on this. I'm not a fan of this rubi red but was only for the prototype. Will print a new one with minor changes and in black

 

[wesmade]

very cool design. Love the spring perches.

very cool design. Love the spring perches.

thanks!


Like the Stones said: "I see a red axle and I want it painted black" :)

more subtle...

 

[dagabba]

Very nice axle, good work!

 

[cooper]

Very nice axle, good work!

thanks!


After more than a year without trails,finally did it!!

Took the JK, the M548 and the 'mog to drive a little. Ended driving the Unimog a lot more than the others

Tried an easy line with sucess and was doing slightly harder lines and the truck was doing great...ended in one that I was positive that will fail...but the truck managed to climb. In 1st gear of course

So cool! This is such a neat build. Congrats on getting it done and out on the rocks.

Thanks! about the rocks...I was really needing it


well, to the news:


that previous axle sparked an old idea of making 100% printed axles. About 4 years ago I worked on that, having housings printed but the big scx10 internals didn't allowed to do them small and nice. Fast forward to the present and adding to my improved 3d skills,we have more choice

Someone suggested TRX4 diff gears and using lockable diff. Was a great idea but the parts are too expensive.Remember that I need 4 sets to make 3 axles. Went to scx10.2 gears from Ebay and they seem good, nice machining and finish

The issue was doing the gear mesh because of the "high pinion" feature but after a few tries, is done


Doesn't seems but it works:

I'm aiming for this,2 halves:

The angle on the pinions is because torque tubes are a possibility. I'm just waiting for parts to arrive to confirm if it's possible
